摘要
地面扬尘在自然风力、机械动力的作用下易产生TSP污染。本文以 1999-2 0 0 1年的监测数据为基础 ,对赤峰市中心城区地面扬尘贡献率进行了估算 ,结果为 43 .1% ,比南方的重庆市 (2 0 .0 % )高出一倍多 ,比北方的长春市高出 7.1%。
The TSP pollution could be emerged easily by the dust of earth's surface,effected by the natural wind and machinery forces.Based on the monitoring data from 1999 to 2001,the contributing rate of earth's surface on TSP pollution is estimated,the result is 43.1 %.It is two times more than the southern city-Chongqin which is 20%,and it is 7.1% higher than the northerncity-Changchun.
